Intact Humoral Immune Response in Patients on Continuous Ambulatory Peritoneal Dialysis

Abstract

After influenza vaccination no statistically significant difference in antibody response was observed between patients on continuous ambulatory peritoneal dialysis (CAPD) and healthy volunteers while a large group of hemodialysis (HD) patients was found to have a significantly lower response rate. This difference remained statistically significant when CAPD patients were compared to a matched HD group. As the antibody formation after influenza vaccination is a T cell-dependent phenomenon, the normal immune response to vaccination suggests an intact humoral and cellular immunity in CAPD patients.
